Programmatic Use

Time increment between the specified date and the desired model simulation
time. The block adjusts the calculated Julian date to take into account the
time increment from model simulation. For example, selecting
Day and connecting a simulation timer to the port
means that each time increment unit is one day and the block adjusts its
calculation based on that simulation time.

If you select None, the calculated Julian date does not
take into account the model simulation time. Selecting this option removes
the first block input.
